Another major prime find by PrimeGrid...and another Canadian connection. :) We are still awaiting contact with the finder (LadyHawk_A321 of Germany). The double checker is Dale Laluk from Canada. He joins fellow Canadians Dylan Bennett, Dave Pickles, and Stephen Kohlman who have all played a part in past significant prime finds. It must be something in the water in Canada. :D

The prime was discovered during the run-up to the Dog Days of Summer Challenge. This is PrimeGrid's first prime for the +1 form in the 321 Prime Search project.
